Close to the port and castle there is a Venetian tower from the 15th century and an Ottoman tower from the 16th. The latter was procured by General Notis Botsaris in 1829 when the city gained independence. The tower features a museum regarding the 1571 Battle of Lepanto and many paintings, gravures, etc. There are also displays regarding churches and rulers of medieval times, as well as wall textiles weaved in Belgium. Worth seeing.
